When a US jury convicted Michael Dunn of attempted murder, but not actual murder, in the shooting death of a black teenager, the hashtag #dangerousblackchildren popped up on Twitter. Users posted photos of black babies and toddlers, making fun of the fear that Dunn testified he felt before opening fire on a carful of teens at a convenience store.

That hashtag was the calling card of Black Twitter, a small corner of the social media giant where an unabashedly black spin on life gets served up in 140-character installments.

Black Twitter shares opinions on everything from President Barack Obama to the latest TV reality show. But Black Twitter can also turn activist quickly.
